Data Aggregation failed in REST API

Hi, I'm creating a REST API on OutSystems.

This service gets data from Database and replies as json.

This service seems to success entity, but fail to get its property(json's property is empty).

Therefore I added breakpoint at REST service, and called REST API, it worked fine!!

I attached REST API image, failed JSON image and success JSON image(when breakpoint was added).

Please give me your advice?

Hi Takahiro,

Can you share the properties of the list append all node?

I'm sorry.

I recreated 'Aggregation Action' and the REST API works well.

So, I can't understand what's wrong and I'll close this post.

Thank for your offer.
